Foldable electric bed

Abstract

A foldable electric bed includes a base mount having a pivot portion, and a swivel mount pivotally connected with the pivot portion by a first shaft, such that the swivel mount is swivelable relative to the base mount between first and second positions due to the limit of first and second contact portions of the base mount. An actuator has a first end pivotally connected with the swivel mount by a second shaft, and a second end pivotally connected with a moveable frame such that the moveable frame is drivenable by the actuator to swivel relative to the base mount. When the swivel mount is swiveled from the first position to the second position, a position of the second shaft is lifted.

What is claimed is: 
     
       1. A foldable electric bed, comprising:
 a base mount; 
 a swivel mount pivotally connected with the base mount by a first shaft, such that the swivel mount is swivelable relative to the base mount; 
 a first moveable frame; and 
 an actuator having a first end pivotally connected with the swivel mount by a second shaft, and a second end directly pivotally connected with the first moveable frame, such that the first moveable frame is drivenable by the actuator to swivel relative to the base mount; 
 wherein the base mount comprises a pivot portion, to which the first shaft is disposed; the pivot portion is provided at a first side with a first contact portion and at a second side with a second contact portion; the swivel mount is swivelable between a first position where the swivel mount is directly in contact with the first contact portion, and a second position where the swivel mount is directly in contact with the second contact portion. 
 
     
     
       2. The foldable electric bed as claimed in  claim 1 , wherein the first shaft is located between the first contact portion and the second shaft, and the second contact portion is located between the first shaft and the second shaft. 
     
     
       3. The foldable electric bed as claimed in  claim 1 , wherein when the swivel mount is swiveled from the first position to the second position, a position of the second shaft is upwardly lifted. 
     
     
       4. The foldable electric bed as claimed in  claim 1 , wherein an elevational position of the first contact portion is higher than an elevational position of the second contact portion. 
     
     
       5. The foldable electric bed as claimed in  claim 4 , wherein the second contact portion is a horizontal surface. 
     
     
       6. The foldable electric bed as claimed in  claim 1 , wherein the base mount comprises a front mount and a rear mount pivotally connected with the front mount. 
     
     
       7. The foldable electric bed as claimed in  claim 6 , wherein the base mount comprises a plurality of support legs mounted to the front mount and the rear mount. 
     
     
       8. The foldable electric bed as claimed in  claim 1 , wherein the first moveable frame has an end pivotally connected with the base mount. 
     
     
       9. The foldable electric bed as claimed in  claim 1 , comprising a second moveable frame having two ends pivotally connected with the base mount and the first moveable frame, respectively.
